74LVTH16835DLRG4

The LVTH16835 consists of 18-bit universal bus drivers which combine D-type latches and D-type flip-flops to allow data flow in transparent, latched, or clocked modes. Data flow from A to Y is controlled by the output-enable (OE) input. This device operates in the transparent mode when the latch-enable (LE) input is HIGH.
The A data is latched if the clock (CLK) input is held at a HIGH or LOW logic level. If LE is LOW, the A-bus data is stored in the latch/flip-flop on the LOW-to-HIGH transition of the CLK. When OE is HIGH, the outputs are in the high-impedance state.
The LVTH16835 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.
The bus driver is designed for low voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment.
The LVTH16835 is fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
